NOSE-GUARD FOR EYEGLASSES.

Specification of Letters Patent.

- Patented Nov. 14, 1905.

Application filed October 16, 1903. Serial No. 177,312.

To all whom, it may concern.-

Be it known that LGEoRen BAUSOH,Of Syracuse, in the county of Onondaga,in the State of New York, have invented new and useful Improvements inNose-Guards for Eyeglasses, of which the following, taken in connectionwith the accompanying drawings, is a full, clear, and exact description.

This invention relates to improvements in nose-guards for eyeglasses inwhich a pair of pneumatic pads are suitably mounted 'upon the frame toimpinge against the sides of the upper part of the nose to hold theeyeglasses in operative position. 7

The object is to reduce the gripping pressure on the nose to a minimumand still pre- 1 vent the glasses from being easily displaced or shakenoff under ordinary usage.

Another object is to enable the pads to readily conform to the contourof the surface of the nose of the wearer without special ad Other usesand objects will appear in the following description,

In the drawings. Figures 1 and 2 are respectively a rear face view and atop plan of a pair of eyeglasses, showing the application of myinvention thereto. Fig. 3 is an enlarged inner face view of one of thedetached noseguards, showing part of the frame and one of the glasses.Fig. 4 is a sectional view taken on line 4 4, Fig. 3.

Similar reference characters indicate corresponding parts in all theviews.

The eyeglasses. as l, are mounted in separate clamps 2, which in turnare secured to the opposite ends of a bow-spring 3 to form thesupporting frame or yoke for the glasses. A pair of nose-guards 4: arealso secured to clamps 2 and preferably by the same means as screws 5,which secure the ends of the spring to the clamps 2. These nose-guardsare substantially duplicates of each other, and each consists of a thinmetal bar 6, having a cup or hollow circular head 7 and a laterallyupwardly projecting arm 8, which is secured directly to its clamp 2 bymeans of one of the screws 5. Each nose-guard is therefore suspendedfrom the screw 5 and is free to spring laterally, and the bars 6areusually disposed in a vertically-inclined position bothlongitudinally and transversely with reference to the glasses, so thatthe cups or heads 7 are nearer to each other than the lower ends of thebars 6 and project beyond the plane of the rear face of the glasses tohold the latter a suitable distance from the eyes when in use.

The cups or heads 7 preferably consist of thin sheet-metal disks whichare concavoconvex in cross-section, as seen in Fig. 4, and are eachprovided with an overturned edge for forming an annular marginal flange9 on the concave side of the disk and an annular groove 10 within theflange. Each of these cups or heads is provided with a circularconcavo-convex pad 11, of rubber or equivalent material, having itsmarginal edge inserted in under the flange -9 in the groove 10 with itsconcave side innermost and facing the concave face of its supportingdisk or head 7.

The open or concave sides of the cups or heads 7 face each other, andthe pads or cushions 11 are, therefore, inserted in the adjacent facesof the heads and held in position by the flanges 9. The adjacent orconvex faces of the pads bulge or project toward each other beyond theadjacent inner faces of their respective cups or heads, and it is thusapparent that an air-chamber is formed between the concave faces of thecup or head and its pad, which constitutes a pneumatic cushion to keepthe pad inflated or extended inwardly. Each of these pads 11 is firstformed into a plain circular disk of greater diameter than the diameterof the groove in which it is to be inserted, so that when its edges areinserted in behind the flange the central portion is buckled or bulgedoutwardly,and the air which is thus inclosed in the cup or head 7operates to maintain this bulge or outward convexity. By thisconstruction of cup or head and pad the latter may be easily and quicklyremoved and a new one reinserted Whenever it may be necessary ordesirable.

It will be observed that the flexible concavoconvex pad, as rubber, notonly affords a light and easy pressure on the nose of the user withoutthe usual pinching eflect, but also holds the glasses in operativeposition with greater certainty than when metal or other hard nose-padsare employed.

The bar 6, carrying the cup or head 7, is provided with a loop or bend12 between the cup or head 7 and arm 8, wherebythe heads in which thepads 11 are inserted may be adjusted vertically or laterally by simplycompressing or extending the loops or bending I TO the portion uponwhich the heads are mounted laterally. This permits the nose-pieces andeyeglasses to be readily and easily adjusted with reference to eachother and to the nose or eyes of-the wearer, and it is an importantfeature of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination with the bow-spring and lens-clamps of a frame foreyeglasses, of a pair of hollow circular heads connected to thelens-clamps and having open sides facing each other, the open side ofeach head having an inturned annular flange forming an annular groove,and flexible pads removably inserted in the open sides of the heads andhaving their marginal edges seated in their respeotive grooves and theircentral portions bowed outwardly to form air-spaces between them andtheir heads.

2. The combination with a lens-supporting frame for eyeglasses, of apair of substantially circular heads mounted on the frame and eachhaving its edge overturned and forming an annular flange and an annulargroove, a compressible and expansible pad for each head, each pad beingcompressed and inserted in its head and entering and held in its groovesolely by its own expansion whereby the pad may be removed or reinsertedat-will.

In witness whereof I have hereunto set my hand this 13th day of October,1903.
